EDWARD GOLD, OF VANCOUVER, BRITISH COLUMBIA, CANADA. I

MACHINE FOR IMPARTING SPIRAL MOVEMENT TO PILES.

To all whom it may concern:

Be it known that-I, EDWARD GOLD, a citizen of the United States of America,- residing at the city of Vancouver, in the Province of British Columbia, Canada, have invented a new and useful Improvement in Machines for I mparting Spiral Movement to Piles, of which the following is a specification.

This invention relates to a machine for applying a spiral wrapping to piles, and comprises a rotatable head having radially operated means for securing the pile concentrically within it, means for rotating suchhead, and means for endwise moving the carriage on which the rotatable head is mounted whereby a spiral movement is imparted to the pile; and in combination therewith a tail carrier for supporting the other end of the pilc, which carrier is provided with means whereby the supporting rollers are adapted to varying dimensions of piles.

The invention is fully set forth in the following specification, reference being made to the drawings by which it is accompanied, in which;

Figure 1, is a side elevation showing the general arrangement of the head and'tail carrier, Fig. 2, an end elevation of the head toan enlarged scale, taken in the direction of the. arrow in Fig. 1, Fig. 3, a side elevation of the same, the upper part of the rotatable head being shown in section on the line A in Fig. 2, Fig. 4, a section of the rim of the head on the line B in Fig. '2, Fig. 5, a detail of the yoke which connects the gear clutches of the driving mechanism, Fig. 6, a detail showing the driving gear of the rotatable head in end elevation, Fig. 7, a side elevation of the same, showing also the connection therewith of the carriage driving gear, Fig. 8, a vertical cross section and end elevation of the tail carrier on the line D D in Fig. 9, and, Fig. 9, a vertical section and side elevation of the same on the line C C in Fig. 8. Fig. 10, is a detail View of a modification of my invention hereinafter again referred to.

in these drawings 2 represents the pile about which a spiral wrapping 9 is to be'applied, and 3 the cylindrical rotatable head within which through which the desired movements are imparted to it. This head 3 is provided with circumferential V shaped grooves 4 in its outer the head is rotatable 9n rollers 5 mounted in a carriage frame 6, which is provided with flanged wheels 7 to run on track rails 8. A flared mouth ring 10 is fitted within the cylindrical head 3 so as to be endwise movable, rotation within the head being prevented by a feather key or keys 11.

Pivotally mounted on pins 12 on the inner side of the mouth ring 10, and on corresponding pins 13, on an inwardly directed flange 14 at the back end of the cylindrical head 3 is a series of links 15 connected in pairs by pins 16, the free ends 17 of which links are rounded and beveled that they will enter into and obtain an Specification of Letters Patent. I Application filed August 20, 1906. Serial No. 331,368.

the pile is secured, and' surface, in which grooves Patented Oct. 15, 1907.

l efficient driving hold on the wood of a pile placed within the mouth ring 10. The links 15 are operated to secure a pile by the retraction within the cylindrical head 3 of the mouth ring 10 which movement by bringing the anchoring pins 12 and 13 of the link system todially inward on the arcs indicated in Fig. 3 and they wise movement of the mouth ring 10 is effected by a series of screws 20, see Fig. 4 each threaded into the mouth ring and rotatable between collars in the back flange 14 of the rotatable head 3. v

The screws 20 are simultaneously operated to effect the endwise movement by pinions 21 secured to the outwardly projecting back end of eachscrew 20, the teeth of which pinions mesh with the internal teeth of a gear ring 22 rotatable on a bearing ring 23 projecting from the back plate of the flange 14 of the rotatable head, which bearing ring fits into a corresponding annular groove in the gear ring 22. The gear ring 22 is also provided with external teeth by which it is rotated ing 27 secured to the carriage frame 6; the shaft 26 being rotated by a worm gear 28 from the shaft 29 of the motor 30 which operates the general mechanism of the carriage and its head. This worm gear is driven through that undue pressure will not be thrown on the centering and securing mechanism. The head 3 itself is rotated by means of a pinion 32 the teeth of which mesh with teeth 33 round the after part of the cylindrical head, and the shaft 34 on which this pinion 32 is secured, is driven by bevel wheels 38, 39 from an intermediate shaft 37 which againis driven from the motor shaft 29 by a pinion 35 on 29 meshing with a wheel 36 on the intermediate shaft 37. The bevel 39 runs free on the intermediate shaft 37 and is connected to drive it by means of the clutch 40 endwise slidable on a feather key in the shaft and operated in and out of driving contact by the'lever 41 The shaft 34 which rotates the head by means of the pinion 32 also carries a worm 45 designed to drive through a worm wheel 47 the driving aide 46 of the carriage 6. This worm wheel 47 runs free on the axle 46 and is connected to drive the shaft 46 by a clutch 48 slidable on a feather in the axle. This traveling gear is designed to move the carriage forward at such a rate of speed in proportion to the rotation of the head that will impart the desired spiral movement to the pile. As it may be necessary however to move the gear must be out of action when the wrapping gear is gether, forces the sharpened ends 17 of the links rawill thus center and securely hold the pile. The endby a pinion 25, secured on a shaft 26 rotatable in a beara conical friction clutch operated by a hand lever 31 so 7 carriage at a higher rate of speed when the rotation of the head is not required, as when the wrapping hav- 1 I ends of the levers 60 at each side of the center-pin 61 that the carriage travels with the pile. The mechan in operation, the wheel 50 is free on the intermediate shaft 37 and is rotatably secured thereto by a clutch face 52 on the same keyed clutch 40 which connects the bevel gear to the shaft 37. To insure that the slow speed gear through the worm and worm wheel 47 is disconnected before the axle 46 is connected to be driven through the gears and 51, the clutches 40 and 48 are connectedso asto be operable together by the lever 41, by a yoke. 53 engaging the grooves of the clutch members, to which yoke the lower end of the lever 41 fulcrumed at 42 on the sector 43 is connected, 'as shown in Fig. 2. By this means when the lever 41 is in the position-shown in Fig. .2 of the drawing the motor 30 will rotate the head 3 and drive the axle 46 to move the carriage 6 on the tracks 8 at'the desired speed to apply the wrapping, as the beveled gear 39 is then clutched to the shaft 37 and will rotate the pinion shaft 38 and the worm wheel 34 on that same shaft is clutched to drivethe axle 46.

Iifthe lever 41 is in the central position on the sector 43, both the bevel wheel 39 and the worm wheel 47 are free on their axles and the motor 30 may be used to secure or release the pile securing device in the rotatable head through the medium of the worm gear 28 and shaft 26. If again the lever is movedover to the pin hole on the extreme left of the sector 43, the bevel gear 39 and worm wheel'45 are still free but the face 52 of the clutch 40 is moved into the recessed engagement of'the gear wheel 50 on theintermediate'shaft 37 and drives the axle 46 at the. higher rate of speed through the gear wheel 51 secured on it. Although this particular method of driving has been specifically described it is not a material point of the application as the. same results may be attained by a.different mechanism. Q

The tail carrier illustrated in Figs. 8 and-9 of the drawings consists of rollers 55rotatablymounted on a mechanism to be described and having peripheral ridges 54 to engage the wood of the'pile 2 and insure ism which carries theroller is supported in a suitable box'frame 56 on a carriage 57 mounted on flanged wheels 58 to run on the tracks 8. The rollers 55 are elevated or depressed to raise or lower and to center a pile: in the axis of rotation of the machine, by mounting the rollers on pins 59 between two linked lever systems. This mechanism is composed of levers 60 connected toward their upper ends to theax'ial pins 59 of the rollers and at their mid length on a pin 61 secured in the sides of the box frame '56. To pins 62 in the lowerends of the levers 60 and to the roller axialpins 59, short links- 63 connect the lower and upper respectively to pins-64 laterally projecting from nuts 65 on right and left hand threads of a screw 66 rotatable in the ends of the box frame56-by m'eansof a crank handle 67. The screw66 passes through and is rotatable in a member 68 from which the center pin 61 projects on each side oi the screw, so that;the weight of the pile which rests on the carrier is transmitted to the frame 56 through-this center bearing member 68, and through the end bearings of'thescrew 66. The upper ends of the levers 60 may be extended upward beyondthe rollers and inwardly curved as at 68 to form guards taneously clutch the bevel gear 39 to rotate to prevent the pile falling off the rollers 55.

seasss In the operation of the device, a pile being slung from an overhead carrier or otherwise suitably supported, the tail carrier 57 is run under one end and its rollers 55 are by means of the crank handle 67 adjusted to center and sustain the weight of that end of the pile. The head carriage 6 is then moved on the tracks up to the other end. and the end of the pile is directed within the rotatable head 3 by the flare of the mouth ring 10. The clutch lever 41 being set in the mid position. where the traveling and rotating mechanism is unclutched. the motor 30 is started and by means of the lever 31 the gear ring 22 is rotated through the friction clutch 28, and operates the several screws 20 to draw the mouth ring 10 inward and the sharpened ends 17 of the linked levers 15 are radially drivendnto the pile centering it in and securing it to the rotatable head 3. The temporary sling or support is then removed and the pile is sustained in the head and tail carriages 6 and 57. The

lever 41 is then thrown over to the extreme left to simulthe head 3 with its secured pile, by means of the pinion 32. and the worm wheel 47 to travel the carriage at the slow speed, by means of the driving axle 46. The combined movement thus imparted to the pile gives the desired spiral movement to it which is the object of the device. On the operation being completed for which the movement is required, the lever 41 is thrown over to the extreme right which unclutches the rotating and the slow speed gear and brings the face 52 of theclutcb into engagernent with the corresponding recessed clutch face of the gear wheel 50 and the carriage is traveled along the. track at the higher speed to deliver the finished pile. tion which frees the clutches from contact with the rotating and traveling gear of the head. and the movement of the motor 30 being reversed the gear ring 22 is operated by the lever 31 to release the centering ends 17 from the pile end and .the pile is free to be removed.

Iffound necessary instead of driving'the carriage 6 through the adhesion of its wheels 7 on the track the wheels-7 may be free on the axle 46 and the movement imparted to the carriage by pinions secured on the axle which'pinions 146 will gear into racks 147 track rails 8 as shown in Fig. 10.
